What will be the first sign of an impending market correction?

I think the question is on many minds these days, but most likely not on Christmas Eve. So this is for the wandering Internet travelers who say, Bah humbug over Christmas and are looking for some predictions or interesting tidbits of information about the stock market. In the chart below I have shown the current trends in the Put to Call ratio and what data point should signal the impending market correction.

I most likely won't be posting any more today or tomorrow but will be back here on Monday when the market is open. In the meantime, wishing you a very Merry Christmas. Drink some Eggnog and just chill.
